用释放不育虫的技术(SIRT)防治侵害贮藏农产品的蛾类是有前途的。由于在储藏烟草的仓库中,仅有烟草粉螟为害,所以用不育技术来防治烟草粉螟是可行的。该虫用Υ射线辐照的不育和亚不育剂量已经确定(Brower,1976)。本文主要研究烟草粉螟亚不育雄虫的交尾竞争能力。材料和方法所用成虫饲养于装有3.8L由Silhacek和Miller(1972)报道的复合饲料的养虫缸里。整 The use of Sterile Insects Release (SIRT) to control moth infestation that hurts agricultural products is promising. Due to the fact that only Nicotiana tabacum is harmed in the warehouse where the tobacco is stored, it is feasible to use sterile techniques to control the Nicotiana tabacum. The insects and the infertility dose of gamma irradiation of the insects have been identified (Brower, 1976). In this paper, we mainly study on the cross-competition ability of the male sterile tobacco. Materials and Methods The adults used were housed in pellets containing 3.8 L of compound feed as reported by Silhacek and Miller (1972). whole
